This mechanical seal is the shaft seal for the Davey XP Series XP900 pressure pump: the pump seal that stops water running along the motor shaft. It fits a 1/2″ (12.7 mm) shaft. It suits pumps using Davey 48802SP. The same seal fits the XP500 and XP700.

Fits the Davey XP900
A replacement mechanical (shaft) seal for the Davey XP900 pressure pump. This seal suits a 1/2″ (12.7 mm) shaft, carbon / ceramic faces and suits pumps using Davey 48802SP. It is the two-part seal that sits behind the impeller: a spring-loaded rotating face on the shaft and a stationary seat pressed into the pump body.
Signs the XP900 seal has failed
- water dripping from between the pump and the motor
- the pump cycling on and off with every tap closed
- a damp patch or rust streak under the motor
Replace the seal as soon as it starts leaking: water tracking along the shaft into the motor is a common way pump motors lose their bearings.
The same seal is used in the Davey XP700, Davey XP Series, Onga Leisuretime LTP400, Onga Leisuretime LTP550, Onga Leisuretime LTP750.
Before you order
Check the old part before fitting: match the size of your old seal.
Measure the shaft where the seal sits and compare the old seal face-to-face with the photos.
